The cooling water leaked from the seal part flows into the water storage part 18, and when the flow-in quantity exceeds a constant quantity, the stored water is discharged outside through the drain passage 19, and reach of the cooling water to the bearing part 13 is thereby prevented. Since a time to be required from the generation of water leak to draining is secured by a water storing function of the water storage part 18, the generation of wrong recognition of a water leak accident when a user sees the drained water during the warm-up operation is prevented.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To prevent step-put or the like by largely reducing the operational amount and improving the stability and responses for phase estimation, for estimating the position of a magnetic pole from an applied high-frequency current.   <P>SOLUTION: The position of the magnetic pole is estimated from a harmonic current extracted from a current iqc at a high-frequency extraction part 34 by injecting a high-frequency voltage into a PM motor 6 from an injection voltage operator 32. For that purpose, a positive-phase axis that rotates in a positive direction, and a reverse-phase axis that rotates in a reverse direction, are defined. Map components for the respective two axes are obtained from a high-frequency current vector. A feature value approximately proportional to a phase error is calculated by integrating or averaging the combined outputs of q-axis components of the map components of the positive and reverse phase axes for a certain period. For estimating the position of the magnetic pole by using the feature value, a feature-extracting operator 35 that calculates the feature value multiplies the high-frequency current component by a sine wave, and takes the average of a period that is integrally multiplied by the cycle of a high frequency.  <P>COPYRIGHT: (C)2004,JPO
